[1/5] zone: zone_config_check_same_setting check for config to edit

  We now check if we get the config, which we edit in this moment and when we continue.

Fixes: #11451

Hi,

this patchset looks fine, but I think the solution is a little bit too
complicated.

Could we not let hook_parse_cmdline() remain untouched and just let it parse all
inputs? We need to parse all arguments anyways before we can make a decision.
We could then check for any conflicts later in hook_edit().

That looks easier to me since:

a) the format of hook_parse_cmdline() would be the same throughout all zones,
ports and configs

b) we do not need to carry around the ID variable. It will be empty any ways
when we are creating a new configuration and then become difficult to handle.

Your thoughts?

Best,
-Michael
